Ennis was also an OSPS operator site, housing long-distance operators.
That function was shut down around 2003.

A schematic dated 11-14-74 shows an L-3 Dallas-Houston coaxial cable route passing through this station.
A later "Spring Maintenance Area" document shows this as an L-5 route.

Ennis is located on the I-45 northbound service road and clearly visible the from freeway.
The site is entered from the south.
In addition to the steel-lattice tower and the large concrete main building, the site also has a multi-door garage-type building and one additional smaller building, indicating an underground entrance.
The site looks like it is not visited on a daily basis but is well-secured with multiple CCTV cameras.
